MRA-5Q

The new MRA-5Q is a system version of a
special receiver MRA-5, an advanced
automatic radio scanner suited for instant
detection of various types of radio bugs in the
frequency range 34-5900MHz. Compared
with the older, very popular MRA-3Q, MRA-
5Q has higher sensitivity on the highest
frequencies, extended frequency range,
improved pulse and digital signal detection,
possibility of the alarm sensitivity adjustment
from the setting menu, correction of DECT
systems and particularly much higher false
alarm resistance.

The basis of the system is the radio
spectrum memory combined with an ultra fast
scanning. The whole frequency range is
scanned every ten seconds and the currently received signals are compared with the initially stored
clean background spectrum. The presence of a new signal activates a three level alarm output. All
new signals with frequency, time and a statistic information are stored in an independent alarm
memory.
MRA-5Q allows to automatically acquire audio records of new signals which have been causing
alarms. Recorded audio samples together with the stored statistic information are reliably indicating if
the object was attacked by RF eavesdropping.
MRA-5Q can be used as a part of the QM-5000 bus system. QM-5000 allows parallel connection of
up to 128 MRA-5Q devices within an object network. The bus system allows full remote control of
each device, and additionally it contains numerous additional features like spectrum analysis in the
range of 34-5900MHz, audio analysis, background statistic, new signal statistic, automatic audio
sampling, frequency and spectrum records, selective statistic, system statistic etc. QM-5000 is not
only a comprehensive solution for object permanent protection, but also a very effective tool for
electronic countermeasures specialists since it gives a clear graphical picture of the current RF
signals. By using QM-5000 we can detect and record even such dangerous systems like spread
spectrum, or modified WiFi, DECT, GSM, UMTS etc.
